We divide 31267971 by 438
The aim is to understand the frequency of 438 in 31267971.

Let's proceed to step 1:
When dividing 3 by 438, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 438

On to step 2:
438 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 438

Step 3:
312 divided by 438 is 0 with a remainder of 312.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 312, we end up with 312.
Append the next digit (6) from the dividend to 312 and continue with: 3126 / 438

Let's proceed to step 4:
When dividing 3126 by 438, we get 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 3066 away from 3126, we end up with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 438

On to step 5:
607 divided by 438 is 1 with a remainder of 169.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 438 away from 607, we end up with 169.
Include the next digit (9) from the dividend after 169, then repeat: 1699 / 438

Moving on to step 6:
438 goes into 1699 3 times with a remainder of 385.
Use 3 as the next digit of our solution. 
Result so far: 713.0
The remainder is 385 after subtracting 1314 from 1699.
Append the next digit (7) from the dividend to 385 and continue with: 3857 / 438

Advancing to step 7:
When dividing 3857 by 438, we get 8 with a remainder of 353.
The number 8 becomes the next digit in our result. 
Result so far: 7138.0
Subtracting 3504 from 3857 leaves us with 353.
Append the next digit (1) from the dividend to 353 and continue with: 3531 / 438

Going ahead to step 8:
When dividing 3531 by 438, we get 8 with a remainder of 27.
The next digit of our result is 8. 
Result so far: 71388.0
If we take 3504 away from 3531, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
When dividing 270 by 438, we get 0 with a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 71388.0
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
If we divide 2700 by 438, we get 6 and a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 71388.06
If we take 2628 away from 2700, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
The number 438 fits into 720 1 times, leaving a remainder of 282.
The next digit of our result is 1. 
Result so far: 71388.061
Subtracting 438 from 720 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 12:
438 can be fit into 2820 6 times, resulting in a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 71388.0616
If we take 2628 away from 2820, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
When dividing 1920 by 438, we get 4 with a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 71388.06164
If we take 1752 away from 1920, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 14:
The number 438 fits into 1680 3 times, leaving a remainder of 366.
Write down 3 as next digit of the result. 
Result so far: 71388.061643
If we take 1314 away from 1680, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 15:
If we divide 3660 by 438, we get 8 and a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 71388.0616438
The remainder is 156 after subtracting 3504 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 16:
438 can be fit into 1560 3 times, resulting in a remainder of 246.
Record the quotient 3 as the next digit in the result. 
Result so far: 71388.06164383
If we subtract 1314 from 1560, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

The final outcome is 71388.06164383, with a leftover of 2.46e-07.
